Patch 4.7 horde composition on garden, athel, magnus and old haunts

Fixed some horde compositions that were spawning incorrectly. This corrected composition should make Garden of Morr, Athel Yenlui, Horn of Magnus, Old Haunts, and some Weaves more difficult.

What actually changed? I played each of these maps several times on cata and it seems like the changes are insignificant because i noticed no difference when playing.

maybe on lower difficulties
